About this Course
With smartphones, smartwatches and even smart appliances, the internet of things has brought us into a world to rival sci-fi novels. We're no longer content with a simple search. We want context. We expect our devices to know our locations, preferences, desires and goals. We expect tailored suggestions, reminders and announcements. Most of the time we don't even realize how much our devices or websites are setup to assist us until our connection is broken or we try to use a different device, and all of a sudden our history and setting aren't there and it's so much harder to do or find anything. Users have come to expect so much and it's just getting worse.
So what does that mean to you as a programmer? How can you make your own applications "user aware"? It starts with data persistence.

Data Persistence on the Web
Data persistence is the means of storing information for a prolonged period of time. We can make applications that are "user aware" by using that information to set user preferences or show use input. We'll cover three ways to persist data in a browser. Forms, Sessions and Cookies. You can also combine these methods with a database or other file system for server based persistence.
